S5. When the remaining amount of condensate at the second atomization assembly 5 is greater than a preset value, control the second atomization assembly 5 to generate heat to atomize the condensate, and control the second fan 994 to drive away the condensate Aerosol formed by the atomization of condensate.

That is to say, when the remaining amount of condensate is so large that the second liquid-absorbing cotton column 51 will not be dry-burned when the second heating element 52 is working, the second atomizing assembly 5 can be controlled to generate heat to atomize the Condensate, thus avoiding supersaturation of condensate that could be ingested by the user. In addition, by controlling the second fan 994 to drive off the aerosol formed by the atomization of the condensate, it can better prevent the aerosol from condensing again in the suction nozzle 1 . It can be understood that the margin can be set according to the size of the volume of the second atomization assembly 5 , and its specific value is not specifically limited here.

Preferably, in the control method, before the step S4, the following steps are further included:

According to the suction end signal, the first fan 993 is controlled to drive the airflow to move toward the air intake slot 36 .

That is to say, after each puff of cigarette is sucked, the gas in the air outlet groove 32 is blown toward the air outlet through the first fan 993, thereby better hindering the flow of residual aerosol and within the present invention. Condensate formed.

Preferably, in the control method, after the step S5, the following steps are further included:

The user's puffing times are counted, and when the puffing times are greater than the preset times and the accumulated amount of condensate at the second atomization assembly 5 is less than the preset value, a condensate leakage alarm signal is issued.

Due to smoking, there will definitely be condensation. As the number of smoking increases, the condensate will inevitably increase. Assuming that the preset number of times is 200 times, if the cumulative amount of condensate is still less than the preset value after 200 suction times, it means that the assembly of the second atomization component 5 is not in place, and the condensate in the mist outlet hole 11 has leaked To other areas, the controller 98 sends a condensate leakage alarm signal, thus well protecting the user's health.

Preferably, in the control method, the step S2 specifically includes:

According to the suction start signal, it is detected whether the suction nozzle cover 200 is set on the suction nozzle 1, and when it is detected that the suction nozzle cover 200 is not covered on the suction nozzle 1, the first atomizing assembly is prohibited 4 generate heat and send a seal failure signal, otherwise, control the first atomizing component 4 to generate heat to atomize the aerosol generating liquid.

After the controller 98 acquires the sucking start signal sent by the airflow sensor 6, it detects whether the suction nozzle cover 200 is set at the suction nozzle 1 through the Hall sensor 992. If the cover 200 is not placed on the suction nozzle 1, it means that the air passage blocking component 7 has failed, and the controller 98 sends a signal of seal failure. This method can not only simply and efficiently detect the airtightness of the air passage blocking assembly 7, but also protect the air flow sensor 6 well. It can be understood that the controller 98 may include a single-chip microcomputer, a speaker electrically connected to the single-chip microcomputer, and a luminous alarm, the speaker is used to send a condensate leakage alarm signal, and the luminous alarm is used to send a seal failure signal.

To sum up, firstly, in the first state, the nozzle cover 200 is separated from the nozzle 1, and the air passage blocking assembly 7 is closed the air outlet groove by the elastic force of the elastic return member 8 32. The airflow sensor 6 is in a closed space, thus preventing condensate from flowing into the airflow sensor 6, thereby improving the service life, and during transportation, the airflow sensor 6 will not be affected by the external Negative pressure causes false triggering; secondly, when inhalation is required, the nozzle cover 200 is placed on the nozzle 1, and the nozzle cover 200 automatically drives the air path blocking assembly 7, so that all The air path blocking component 7 opens the air outlet groove 32, and at the same time, the liquid push plug 2001 pushes the condensate in the mist outlet hole 11 to flow toward the second atomizing component 5, so that the user will not inhale the suction nozzle 1 during the inhalation process. The condensate at the place, and after inhalation, the second atomizing component 5 can atomize the stored condensate to avoid excessive condensate retention, thus better protecting the air flow sensor 6 .
